JOURNAL-BOX.

' Patented Auf. 23, 1910.

Application led August 29, 1908. Serial No. 450,872.

To all whom it mayy concern: l

Be it known that I, lYiLLIAM G. DUxiL-iw, a citizen ofV the United States, residing :it Brantford, in the county of Brant, Province lof Ontario, Canada, have invented certain new Vand useful Improvements in Journal- Boxes,'ot` which the followingis a specification.

My invention relates to journal boxes for railway trucks.

rl`he object of my invention, is to provide an improved form of lid or cover which will render the `box easily accessible for inspection or repairs.

A further object, is to provide a lid which vwill allow thc use of the box with a low down body or frame.

A further object, is to provide a journal boxliaving a lid which when open, may be utilizedvas a shelf during the operation of renewing the journal bearing key, brass and packinff.

A further object, is to provide a journal box lid, which will be as far as possible, dust proof and oil tight, andof simple and economical construction.

A lurther object, is to dispense with the ruse of all pins, rivets, or bolts generally einployod for securing` the lid tothe journal linx. 7

A further object, is to provide a journal box having?r means for attaching thclid thereto, which is all inclosed within the walls of the box, thus making it impossible for any ot' the parts to become lost.

A further object is to provide a lid which cannot be opened except by the use of a proper tool.

My invention consists generally in a journal box having its lid hinged at its lower end. ou the box.

Further, the invention consists in a spring mechanism normally secureljv locking the lid in its raised or closed position, but adapted to hold the lid when it is swung down to a horizontal or open position.

Further the invention consists in improved means for pivoting the lid in the box whereby it. is held securely in place, thus reducing liabilityY of heated journals due to loss of journal box lids, suitable means being pro vided whereby the journal box lid may be removed when necessary.

Further 'the invention consists in seating the lid in the wall of the box, whereby it. will be rendered practically dust proof, and oil tight.

Further the invention consists of various constructions and combinations, all as hereinaiter described, and particularly pointed out in the claims.

In the accompanying drawings forming Y part of this specification, Figure l, is a trontelevation of a journal box with a por tion of its wall broken away, illustrating the manner of mounting the lid therein. Fig. 2, is a sectional view of the box showing, the lid in its closed position, Fig. 3, is a detail sec tional viewshowing the lid open. illustrates a portion of the wall of the box with the lid removed therefrom. Figs. 5

` and (i and T, are detailed views of the lid.

In the drawing, 2 represents the journal box and 3 the lid. Generally in boxes of this kind, the lid is hinged at the top and is swung upward by the inspector to open the box and inspect the bearing. W'hen the lid is hingedy at the top of the box, it frequently cannot be swung high enough to permit. convenient inspection of axle, brass and packingr as the lid will come in contact with the car body or its :trame work.'`

The tendency in modern railway car construction, is to set the car body as low as practicable. and this construction, I have made possible, by hinging my journal box lid at the bottom and allowing it to swing outwardly to a. horizontal position where it will not only permit convenient access to and inspection of the box, but will serve as a shelf on which articles removed from the box ma)v be temporarily placed.

The journal box and the lid are of the same construction on both sides, and hence a detailed description of one or" the hinges will be snliicient. it. being understood that both edges of the lid are supported in the same manner. The wall of the box has a recess et adapted to receive a pivotI pin 5 which projects laterally from a flange (i on the lid 3. This pivot pin fitting within the recess et forms a hinge for one side of the lid. A seat T, is provided in the wall of the box, and a flange S incloss the scat and forms with the lid, a dust proof joint. A stop 9 is provided on the lid in a position to engage the edge l0 of the recess 4, and prevent vertical vibration of the lid. At the lower end of the lid, webs 11 are formed having projections l2 which overhang the wall 13 and rig. 4,'

are recessed to receive the edge of said wall and forni therewith. a close joint to retain the oil and prevent the entrance of dust and dirt into the ybox under the lower edge of the lid. A bracket 1l forms a continuation of the flange G and has recesses 15 and 1G in its edge between which a curved cam track 1T is'formed. The wall of the box on each side, provided with a projection or hoiisinf r 1S in which is a sliding spring detent 1S), adapted to receive oneeiid of a coiled springf Q0, that is seated at its upper end in a recess 21. An opening 22 leads through the wall of the b: x into the housing 1S and said opening communicates with a slot 23 in which a lug 2l formed on the detent. 19 is slidable. This lug, is adapted to bear on the edge of the bracket. 14 and ride thereon during the movement. of the lid.

within the recess 15 and having swung past the center of the lid pivot, the vtension of the spring will beexerted to hold the lid in its open position. The lower end of the lid, contacts with the wall of the box as indicated in I4` ig. 3, and forms a stop to limit thedownward movement of the lid. Vlien the lid is closed,tlie bracket 1l swings down within a. housing which serves as a guard for the bracket and prevents the journal packingr from working therein. I also prefer to provide a series of teeth 2G on the wall of the housingand also on two webs 26 which extend inwardly from the front wall of the box. These teeth engaging the packing. prevent upward creeping of the saine. 27 therein. into which a pin may be thrust when the detent is adjusted in the position shown in Fig. 4, for the purpose of relieving the lid of the pressure of the spring, and allowing it to be easily removed from the box. To apply the lid to the journal'box, place the spring detent in its socket and insert the spring. then raise the spring detent and lock it by means of the retaining pin. insert the. pivot pin in recess 4 leaving the lid in an open position, then remove the retaining pin, and the lug on the spring detent will be moved into contact with the lid bracket, and the lid be held thereby, either iii an open or closed position. Vhen the lid is in an open position, it will be securely held and should the spring become weak iii case of excessive heating of the journal box, the lid cannot become detached and lost.

The spring detent 19 has a socketl It will be noted that the. lid and its con-' nections are all cast. in one piece, thereby saving considerable expense in the manufacture of the journal boxand obviatiiig entirely the danger of losing the parts and makingfewer joints than are usually found in boxes of this kind.

The lid of the box when closed, tits snugly within the flange 8 and it. will be impossible for any inischievously inclined person to pose ot' pulling the lid to an open position.

liii 25) will be substantially flush with theouter face of the lid, and will have no projecting parts which might strike sonic other object and cause damage to the box.
